Most AI notetakers limit you to ~300min/month. As a student with 60+ hours of lectures, that wasn't enough. So I built Alt. It runs local AI models on your Mac for unlimited, free, private transcription. Optimized for the Apple Neural Engine, it uses minimal battery and needs no internet. Now supporting 100+ languages and optional Pro access to SOTA models like GPT-5.1 & Gemini 3 for advanced summaries.
